North Dakota has no restrictions on at-home paternity testing. You can order a kit, collect DNA samples at home, and mail them to a lab without any state-level barriers. If you want a private answer about biological paternity, any North Dakota resident can do it.
North Dakota adopted the 2002 Uniform Parentage Act at Chapter 14-20 of the North Dakota Century Code, retiring the older 1975 UPA (Chapter 14-17). Signatories get a 60-day rescission window for the state's Acknowledgment of Paternity (Form SFN 8195), and a post-window challenge is limited to fraud, duress, or material mistake of fact within two years. What sets North Dakota apart is what happens next: even when a putative father brings a valid challenge, North Dakota courts apply a best-interest-of-the-child balancing test before ordering post-acknowledgment genetic testing. A judge can deny a DNA test outright if disrupting the child's existing family relationship would cause more harm than the truth is worth. That gate makes the private, at-home biological answer especially valuable in North Dakota: you may never be able to get it through the court.
Below: how North Dakota defines paternity, the voluntary acknowledgment process, the 60-day rescission rules, the best-interest gate on court-ordered testing, and where at-home DNA testing fits in.
How North Dakota Law Defines Paternity
North Dakota's paternity framework is in North Dakota Century Code Chapter 14-20, the North Dakota Uniform Parentage Act. The current chapter took effect after the state repealed former Chapter 14-17, which had adopted the 1975 UPA.
Marital presumption: Under § 14-20-10, a man is presumed to be the father of a child if he and the child's mother are married and the child is born during the marriage. The presumption also applies if the child is born within 300 days after the marriage is terminated by death, annulment, declaration of invalidity, or divorce. A holding-out presumption also applies: if the man resided in the same household with the child for the first two years of the child's life and openly acknowledged the child as his own, he is presumed to be the father. These presumptions are rebuttable through the acknowledgment or adjudication process.
Who can bring a paternity action: Under Chapter 14-20, a proceeding to adjudicate parentage may be brought by the child; the mother; a man whose paternity is to be adjudicated; the state's Child Support Division; an authorized adoption agency; or a representative of a deceased, incapacitated, or minor party.
Voluntary Acknowledgment of Paternity in North Dakota
For unmarried parents who agree on who the father is, North Dakota offers a voluntary Acknowledgment of Paternity — the state's official form is SFN 8195. It is the simplest way to establish legal fatherhood without going to court.
The acknowledgment is governed by § 14-20-14 and filed with the Division of Vital Records within the North Dakota Department of Health and Human Services. Most acknowledgments are executed at the hospital within three days of birth, when hospital staff provide the form to unmarried parents. Parents who did not sign at the hospital can complete Form SFN 8195 through Vital Records or a Child Support Division office.
Both parents must sign voluntarily. Neither party can be pressured or coerced. Once filed, the acknowledgment has the same legal effect as an adjudication of parentage — the same support obligations, the same parental rights, and the father's name added to the birth certificate through the Division of Vital Records.
If you are unsure whether you should sign, consider getting a private answer first. A home paternity test costs $79 and gives you results in days. Those results will not hold up in a North Dakota court, but they can help you make an informed decision before signing a legal document that becomes very difficult to undo — especially given the best-interest gate that later challenges have to clear.
Rescinding or Challenging a Paternity Acknowledgment in North Dakota
The rescission and challenge rules have a short first window, a narrow second window, and then a distinctive judicial screen even inside that second window.
The 60-Day Rescission Window
Under § 14-20-16, a signatory may rescind an acknowledgment of paternity by commencing a proceeding to rescind before the earlier of:
- 60 days after the effective date of the acknowledgment, or
- The date of the first hearing, in a proceeding to which the signatory is a party, before a court to adjudicate an issue relating to the child, including child support.
The rescission window can close before day 60 — as soon as any court proceeding involving the child has its first hearing. Do not wait if there is any active case involving the child.
Challenge After the 60-Day Window
Once the 60-day window closes, North Dakota allows a challenge under narrow conditions. Under § 14-20-17 and the statute of limitations at § 14-20-44, a signatory may commence a proceeding to challenge the acknowledgment only on the basis of fraud, duress, or material mistake of fact, and only within two years after the acknowledgment is filed. The challenger carries the burden of proof.
Here is where North Dakota diverges from most UPA states. Even inside the two-year window, and even when the challenger states a valid fraud or mistake-of-fact claim, North Dakota courts apply a best-interest-of-the-child balancing test before ordering genetic testing. This is court-applied practice under Chapter 14-20 rather than a specific statutory subsection. The court weighs factors such as the length of time since the acknowledgment was executed, the nature of the relationship between the child and the acknowledged father, the age of the child, the potential emotional impact of learning the acknowledged father is not the biological father, and the harm that may result from disrupting the child's existing family relationships. If the court determines that testing is not in the child's best interest, it can deny the motion outright.
In some post-acknowledgment cases, a putative father with real biological doubts will never be granted a court-ordered DNA test at all. That is why a private biological answer, obtained early, matters more in North Dakota than in states without this judicial screen. For $79, a home paternity test gives you a private biological answer regardless of what any future court decides.
North Dakota's Paternity Adjudication Process
When paternity cannot be resolved through a voluntary acknowledgment, North Dakota provides both a judicial and an administrative path.
Judicial path: A petition to adjudicate parentage is filed in North Dakota district court. Under Chapter 14-20, the court has authority to order genetic testing of the mother, the alleged father, and the child, and to enter findings on parentage after a hearing. Both parties can present evidence, including DNA test results collected under chain of custody.
Administrative path: The Child Support Division within the North Dakota Department of Health and Human Services handles administrative paternity establishment as part of child-support case processing. The division can order genetic testing, review results, and pursue administrative or judicial paternity orders as appropriate.
For a broader overview, see our guide on how to establish paternity.
Court-Ordered and Administrative Genetic Testing in North Dakota
North Dakota courts and the Child Support Division both have authority to order genetic testing in paternity cases, subject to the best-interest analysis discussed above when the case involves a challenge to a filed acknowledgment.
The dual 99% probability and 100-to-1 CPI rule: Under § 14-20-37, a man is identified as the father of a child if genetic testing complies with the statute and the results disclose both of the following:
- A probability of paternity of at least 99%, using a prior probability of 0.50; and
- A Combined Paternity Index of at least 100 to 1.
Both figures must be met simultaneously. Well-run labs analyzing 20 or more markers typically clear both figures on a true biological match, but the statutory language sets a clear dual bar rather than relying on either metric in isolation.
Exclusion results: If genetic testing shows the man is not the biological father — an exclusion — that result rebuts the presumption of paternity and can be presented to the court as evidence in a proceeding to adjudicate parentage.
Mandatory submission to court-ordered testing: When a North Dakota court orders genetic testing under Chapter 14-20, each party in a contested paternity case must submit. Refusal can result in the court enforcing its order or entering adverse inferences against the refusing party. For more on this, see our article on what happens if you refuse a paternity test.

North Dakota Department of Health and Human Services Child Support Division
The Child Support Division, within the North Dakota Department of Health and Human Services, handles paternity establishment and child-support enforcement for the state.
The Child Support Division can:
- Establish paternity for children born to unmarried parents
- Arrange genetic testing when paternity is in question
- Locate noncustodial parents
- Establish, modify, and enforce child-support orders through administrative and judicial processes
- Distribute child-support payments to families
If a custodial parent applies for child-support services and the father has not been legally established, the division assists with the paternity process — helping parents complete Form SFN 8195 or, if the alleged father is unwilling to sign, arranging DNA testing. The division does not represent either parent but assists both sides.

At-Home vs. Legal Paternity Testing in North Dakota
North Dakota does not restrict at-home DNA testing. Residents can purchase and use a home paternity test without any special permissions — no doctor's order, no state approval, no advance filing.
The one critical limitation:
At-home paternity test results are not admissible in North Dakota courts.
Home test results are considered "peace of mind" testing. The lab science is the same as a legal test, but without chain of custody documentation — witnessed collection, ID verification, tamper-evident seals — a North Dakota district court or Child Support Division administrative hearing will not accept them as evidence.
If you need results for a legal matter in North Dakota — child support, custody, challenging a voluntary acknowledgment, or contesting an administrative order — you will need a legal paternity test with full chain of custody. That means professional sample collection at an approved facility with ID verification and witnessed handling.
Given North Dakota's best-interest gate on post-acknowledgment testing, many residents choose to start with a home test well before any court process. It costs less, results come back in days, and it gives you a clear biological answer regardless of whether a court would ever order testing in your case. We cover the differences in more detail in our comparison of home vs. legal paternity testing.
How At-Home DNA Testing Works
The DNA testing process works the same way regardless of where you live:
- Order your kit. You can order a home paternity test kit from US Diagnostics Center for $79. The kit ships to your North Dakota address and includes a prepaid return envelope.
- Collect samples. The kit includes cheek swabs for the alleged father and the child. Rub the swab on the inside of each person's cheek for about 30 seconds. No blood, no needles.
- Mail samples back. Seal the samples in the provided packaging and drop the prepaid envelope in the mail.
- Lab analysis. Once the lab receives your samples, processing takes 2-3 business days. Our lab analyzes up to 28 genetic markers — well above the industry standard of 20 or more markers.
- Get your results. Results are delivered securely online. You'll see either an inclusion (99.99% or greater probability of paternity) or an exclusion (0% probability).
The mother's sample is not required but can strengthen the analysis. A mother's kit and express result options are available during checkout.

Frequently Asked Questions
Can I use a home paternity test as evidence in a North Dakota court?
No. North Dakota district courts and Child Support Division administrative hearings require chain of custody documentation for DNA evidence — witnessed collection, government-issued ID verification, and tamper-evident packaging. A home test skips all of that. The results are scientifically accurate and fine for personal knowledge, but they will not be admitted as evidence. For any legal matter, you need a legal paternity test collected at an approved facility.
What is the best-interest gate on post-acknowledgment DNA testing in North Dakota?
North Dakota courts do not automatically order genetic testing just because a signatory files a challenge to an acknowledgment. Even inside the two-year challenge window under § 14-20-44, and even when the signatory states a valid claim of fraud, duress, or material mistake of fact, the court will weigh whether ordering genetic testing serves the child's best interest. Courts look at how long the acknowledgment has been in place, the strength of the parent-child relationship, the age of the child, and the potential emotional impact of disrupting the existing family. If the court concludes that testing is not in the child's best interest, it can deny the motion. This is a matter of court-applied practice rather than a fixed statutory formula, and it makes an early, private biological answer especially useful in North Dakota.
How long do I have to rescind an Acknowledgment of Paternity in North Dakota?
Under § 14-20-16, you have 60 days from the effective date of the acknowledgment, or until the date of the first court hearing in a proceeding involving the child — whichever comes first. After the rescission window closes, § 14-20-17 and § 14-20-44 let you challenge the acknowledgment only on the basis of fraud, duress, or material mistake of fact, and only within two years of the effective date. Even inside that two-year window, the court applies a best-interest analysis before ordering DNA testing.
Where is Form SFN 8195 filed in North Dakota?
Form SFN 8195, the North Dakota Acknowledgment of Paternity, is filed with the Division of Vital Records within the North Dakota Department of Health and Human Services. Most acknowledgments are executed at the hospital within three days of birth, but the form can also be completed later through Vital Records or a Child Support Division office.
What is North Dakota's marital presumption of paternity?
Under § 14-20-10, if the mother is married when a child is born, or the child is born within 300 days after the marriage ends by death, divorce, annulment, or a declaration of invalidity, the husband is presumed to be the child's father. North Dakota also recognizes a holding-out presumption: if the man resided with the child for the first two years of the child's life and openly acknowledged the child as his own, he is presumed to be the father. These presumptions are rebuttable through the acknowledgment or adjudication process.
Does the Child Support Division provide free paternity testing in North Dakota?
The Child Support Division can arrange genetic testing as part of an active child-support case. When the division orders the testing, the cost is typically advanced by the agency, with allocation of cost addressed in the eventual order. If you are pursuing paternity testing outside a division case, you will need to arrange and pay for testing yourself. Application details are available through the North Dakota Department of Health and Human Services.
